I know this is off topic, but I do not seem to have access to any
astronomy conferences here at my pnet node, and this seems
as close as I could get.
Does anyone know how astronomers can judge the distance of
objects from the images they cast?  That is, if one view the
light from a distant star or galaxy, how can one determine the
distance that the light has ttraveled?
